Hi.
1st thanks for your kind comments.
Answering to johnnyhay, I usually render my scenes with povray (there's a plugin for blender to export to povray), but this time it was done using blender internal engine.

Also, where's the url for your background?

The background for this wallpaper, as it shows in the screenshot of my 1st post, is generated by kde.

Go to KDE's Control Center :: Appearence and Themes :: Background
In Background change the following:

Picture: sabayon_new02.png

Options:
Position: Centered
Colors: Night Rock by Tigert
(Color to the left):#7E0000
(Color to the right):#FFB109
Blending: No blending

Then click the Applay button, close Control Center and you are done.
I hope that answers your question.
Bye.
